• P0001 ? no such code for 05 Ford Expedition . This not a Ford code, take it to a qualified repair shop that has a proper scan tool, not a cheap code reader .

  Vehicle does not use fuel regulator, has FPDM - fuel pump driver module and a fuel rail pressure sensor to control fuel flow . The PCM - engine computer uses input info from fuel rail pressure sensor to know what duty cycle info to send to the FPDM - to command fuel pump on time. Suggest you view video

  Also be aware that the location of the FPDM is under the vehicle in the back mounted on the frame rail or above the spare tire on axle housing and they corrode and short out.
  

Thanks Jeff.

Fuel pump is located inside the fuel tank. You have to drop tank to gain access. Try changing the fuel filter which should be located underneath near the drivers door next to the frame

The fuel pump relay is not servicable, it is integral to the central junction box.

it could be a fuse or a bad ground some were.

If it a diesel then you must be aware that when changing a filter and pump they must be full of fuel, otherwise it won't **** the fuel into the engine.

Fuel pressure test , is there spark ? Videos on youtube showing how to check .

OK, there are fuses on the driver's side down below.

But, if you are having a fuel pump problem, it's likely that the fuse is alright and you need to replace the fuel pump. Same thing happened to our 1999 Ford Expedition Eddie Bauer Edition. It quit working. And the inertia fuel cutoff switch didn't help, either (flipping or pushing it).

So, if you have no fuel coming, it may very well be the fuel pump.

We changed ours around 112000mi.

First you need to verify that the pump is getting power. Did you check the Inertia Switch? Power goes through that switch to the fuel pump. If the switch is good, and getting power,the fuel pump is most likely bad, the fuel tank must be lowered to replace the fuel pump.

fuel pump went out; my suggestion is to support vehicle and lower gas tank and change the fuel pump
